WebMay 1, 1992 · Diastereoisomers and geometric isomers are both chemically distinct and pharmacologically different (unless they are interconverted in vivo) and are generally readily separated without chiral ... WebMethedrine during the 20th century was a 50:50 racemic mixture of both methamphetamine isomers (levo and dextro). Wallach's rule. Wallach's rule (first proposed by Otto Wallach) states that racemic crystals tend to be denser than their chiral counterparts. This rule has been substantiated by crystallographic database analysis. …
